Null pointer dereference using st_imu68 driver and STMems_Android_Sensor_HAL_IIO

[DevM]

Hi all,

I opened a issue on github about it:

https://github.com/STMicroelectronics/STMems_Android_Sensor_HAL_IIO/issues/6

Once i add the STMems_Android_Sensor_HAL_IIO library on my system the sensor service crash.

I don't know if this is the official way to report a bug, Otherwise let me know the right way to do it.

Thank you in advance.

Hi @DevM​ ,

you are right, the official way to open an issue concerning those Android libraries is reporting it on Github.

Same for the C libraries, for example.

Please let me know if you will or will not receive a feedback (in about 1 week max).

Edit: the topic should now be closed on Github.
